Principle of Heat Transfer Capacity Test

Testing Requirements

1)Heating input-power is supplied by the special delicate power adjustment;

2)heat pipe is placed with a α inclination angle;

3)when the fluctuate of the supervisory temperature on the outer shell is within 0.5℃ in 5min, the heat transfer process reaches its balance and the maximum heat transfer capacity (Qmax) is also defined simultaneously.
